Abstract
A method for heating surfaces includes heating the surface of a hole by inserting a magnet cylinder into the hole and rotating the magnet cylinder, heating the surface of a hole by inserting a magnet stack into the hole and reciprocating the magnet stack, or heating a selected area of a workpiece surface by positioning a magnet disc adjacent the selected area and rotating the magnet disc. In each case, eddy currents are produced, inducing heating of the surface.
